Hierarchical Parallel Programming Model and Parallelization and Optimization Techniques Based on SMP Cluster

Zhenghua Wang

Open publisher page 1 citations

Abstract

This paper describes the hybrid parallel programming model MPI/OpenMP which is suitable for the hierarchical architecture of SMP cluster in detail.It also provides the inter-and intro-node hierarchical parallelism.Then combined with an available performance evaluation method,a number of effective parallelization and optimization techniques on the MPI,OpenMP and single-processor three levels are introduced respectively.Meanwhile,we emphasize that performance optimization on single-processor is an important issue which cannot be ignored for improving parallel program performance.
